This makes it clear we're dealing with a message which is a wrapped error
reply (needing unwrap_onionreply), not an already-wrapped one.

`wallet_payment_store` would free the `wallet_payment` instance which would
then cause us to reload it from the DB. Instead of doing the store->free->load
dance we now tell `wallet_payment_store` whether it should take ownership and
leave it alone if not.
Passing the payment around instead of referencing it through payment_hash and
partid is a nice side-effect.
This is the final step: we pass the complete fee_states to and from
channeld.

This is a transient field, so rework things so we don't leave it in
struct htlc_out. Instead, load htlc_in first and connect htlc_out to
them as we go.
This also changes one place where we use it instead of the am_origin
flag.

This is in preparation for partial payments. For existing payments,
partid is 0 (to match the corresponding payment).

If we can't decode the onion, because the onion got corrupted or we used
`sendonion` without specifying the `shared_secrets` used, the best we can do
is tell the caller instead.
This means that c-lightning can now internally decrypt an eventual error
message, and not force the caller to implement the decryption. The main
difficulty was that we now have a new state (channels and nodes not specified,
while shared_secrets are specified) which needed to be handled.
We are breaking with a couple of assumptions, namely that we have the
`path_secrets` to decode the error onion. If this happens we just want it to
error out.
In a future version, we will use features to insist that payers
provide the secret. In transition, we may have old invoices which
didn't insist on that, so we need to know this on a per-invoice basis.
Not sure if I got the right syntax for adding an empty blob though!

1. Printed form is always "[<nodeid>-]<prefix>: <string>"
2. "jcon fd %i" becomes "jsonrpc #%i".
3. "jsonrpc" log is only used once, and is removed.
4. "database" log prefix is use for db accesses.
5. "lightningd(%i)" becomes simply "lightningd" without the pid.
6. The "lightningd_" prefix is stripped from subd log prefixes, and pid removed.

Changelog-removed: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field.
We were implicitly relying on sqlite3 behavior that returns the zero-value for
nulled fields when accessing them. This adds the same behavior explicitly to
the DB abstraction in order to reduce `db_column_is_null` checks in the logic,
but still make it evident what is happening here.

`shutdown_scriptpubkey[REMOTE]` is original remote_shutdown_scriptpubkey;
`shutdown_scriptpubkey[LOCAL]` is the script used for "to-local" output when `close`. Add the default is generated form `final_key_idx`;
Store `shutdown_scriptpubkey[LOCAL]` into wallet;
This triple join should be efficient to read, and to process. We have a
one-to-many (tx-to-annotations), followed by a
one-to-one (annotation-to-channel) join, so we are limited to annotations x
transactions results.
We have split the iteration over the txs and the output in different
functions, so pushing the annotation down, while keeping the transaction
addition atop. This showcases the need to not have the txid reference the
transactions.id in the DB: we annotate in a function that doesn't have the tx
index context, but only add the TX after we have finished extracting.
Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

The DB field type has to match the size of the accessor-type, and we had to
split the `REPLACE INTO` and `INSERT INTO OR IGNORE` queries into two
queries (update and insert if not updated) since there is no portable UPSERT
operation, but impact should be minimal.

sqlite3 will just report 0 for anything that it thinks should be numeric, or
is accessed using a numeric accessor. Postgres does not, so we need to check
for is_null before trying to read it.

This was weird right from the start, so we just split the table into integers
and blobs, so each column has a well-defined format. It is also required for
postgres not to cry about explicit casts in the `paramTypes` array.

This is the counterpart of the annotations we did in the last few commits. It
extracts queries, passes them through a driver-specific query rewriter and
dumps them into a driver-specific query-list, along with some metadata to
facilitate processing later on. The generated query list is then registered as
a `db_config` and will be loaded by the driver upon instantiation.

We will soon generalize the DB, so directly reaching into the `struct db`
instance to talk to the sqlite3 connection is bad anyway. This increases
flexibility and allows us to tailor the actual implementation to the
underlying DB.

`db_select_prepare` was prepending the "SELECT" part in an attempt to limit
its use to read-only statements. This is leads to the queries in the code not
actually being well-formed, which we'll need in a later commit, and was also
resulting in extra allocations. This switches the behavior to just enforce a
"SELECT" prefix being present which allows us to have well-formed queries in
the code again and avoids the extra allocation.

We need to have full DB queries that can be extracted at compile time later in
order to be able to rewrite them in other SQL dialects. In addition we had a
bit of unnecessary code-duplication in db_select and db_select_prepare. Now
the former uses the latter internally.

These will interfere with our query extraction process later on, and they were
really separating definition from use anyway, so let's expand these field lists.
